MODE(S) FOR CARRYING OUT THE INVENTION

(6) FIG. 1 is a schematic, exemplary illustration of a housing 10 of a fire alarm and/or extinguishing control station. The housing 10 has a housing body 20 which is closed at the front side by a housing door 30. The housing door 30 terminates flush with the housing body 20 at the outer sides so that, in this embodiment, there is no perceptibly protruding transition between the housing body 20 and the housing door 30. The housing 10 is mounted at the application location, for example, in the orientation depicted on a wall. The housing 10 may, however, also have clearly different shapes and, for example, be constructed for erection on a floor.

(7) An outer side 32 of the housing door 30 faces an observer standing in front of the housing 10. A display and/or operating component 36 arranged on the outer side 32 of the housing door 30 enables the observer to obtain important information relating to the fire alarm and/or extinguishing control station, for example, information regarding which participants, for example, fire alarm, signals an alarm or a fire without it being necessary to open the housing 10.

(8) FIGS. 2a to 2e show different steps of an operation for opening the housing door 30 in a first embodiment. The housing 10 substantially corresponds to the housing of FIG. 1, wherein in addition a gripping element 38 which is constructed as an angular member is shown at the upper side of the housing door 30.

(9) In FIG. 2a, the housing 10 is in a partially open state, wherein the housing door 30 is partially rotated about a vertical axis close to a left side face of the housing body 20.

(10) The partially open housing door 30 enables a view through an opening 22 of the housing body 20 into the inner space 12 of the housing 10. In the closed state of the housing 10, the opening 22 is closed by the housing door 30, wherein the housing door 30 surrounds a sealing edge 26 which protrudes from a front side 24 of the housing body. By the sealing edge 26 protruding in front of the front side 24, the usable inner space 12 is increased in comparison with the case in which the sealing edge is provided offset in an inward direction.

(11) In the inner space 12, modules 16 which are part of the fire alarm and/or extinguishing control station are shown by way of example. To the module 16, external components, for example, alarms, extinguishing units, alarm means, etcetera, can be connected by means of limit values lines or other connection lines. Other embodiments of fire alarm and/or extinguishing control stations may also be monolithic and consequently not module-based or a mixture of both.

(12) The opening of the housing door 30 is carried out by means of a hinge device 40 which is still concealed by the housing door 30 in the view of FIG. 2a.

(13) FIGS. 2b and 2c show other views in which the housing door 30 continues to be further opened. In the inner space 12, it is further possible, for example, to see a module bar 14 to which the modules 16 are fitted. Furthermore, two hinge elements 44 of the hinge device 40 can be seen and are fitted at different heights to the left side face of the housing body 20 and an inner side 34 of the housing door 30.

(14) The hinge elements 44 define a first rotation axis 41 and a second rotation axis 42 which are spaced apart from each other by approximately 50% of the width of the housing door 30. Up to the opening position shown in FIG. 2c, an opening of the housing door 30 is carried out only by means of a rotation about the first rotation axis 41. The second rotation axis 42 is unchanged in comparison with the closed position of FIG. 1, that is to say, as far as this position, there was no rotation about the second rotation axis 42.

(15) From FIG. 2c to FIG. 2e, the housing door 30 was now pivoted about the second rotation axis 42 back in the direction of the original orientation. In FIG. 2e, the rotation about the second rotation axis 42 is terminated and the outer side 32 including the display and/or operating component 36 is from a position in front of the opening 22 of the housing body 20 at the same time as the inner space 12 within access of an observer, for example, a service technician. By the spacing between the first rotation axis 41 and second rotation axis 42 substantially corresponding to half the housing door 30, the opening 22 is completely accessible and at the same time there is no gap provided between the housing door 30 and housing body 20.

(16) The position with respect to the first rotation axis 41 is identical in FIGS. 2c to 2e shown by way of example and only a rotation about the second rotation axis 42 is illustrated. The rotations about the first rotation axis 41 and second rotation axis 42 may naturally also be combined and carried out at the same time. The first rotation axis 41 may enable any opening angle, for example 180° or more, and is not limited to the opening angle of approximately 100° shown in the example.

(17) The rotation axes may be defined in such a manner that the first rotation axis 41 defines a rotation of the hinge device 40 with respect to the housing body 20, whilst the second rotation axis 42 defines a rotation of the hinge device with respect to the housing door 30. The rotations about the first rotation axis 41 and second rotation axis 42 are additive as a result of the parallel nature of the rotation axes so that the sum of the rotation about the first rotation axis 41 and second rotation axis 42 produces the rotation of the housing door 30 with respect to the housing body 20. As a result of the opposing rotation about both rotation axes, the rotation of the housing door 30 with respect to the housing body 20 is accordingly reduced or even completely cancelled.

(18) FIGS. 3a to 3d are schematic cross-sections of another embodiment of a housing 10 according to the invention. The housing 10 of FIG. 3a to FIG. 3d differs from the example of FIG. 2 in the configuration of the hinge device 40.

(19) In this embodiment, the hinge device 40 has four preferably identical hinge elements 46 which are each arranged in pairs at a left and right side face of the housing body 20 and which enable a vertical parallel guiding of the housing door 30. The hinge elements 46 are in this embodiment constructed in a staircase-like manner with two steps of different lengths. So that the hinge device 40 in the closed state, which is shown in FIG. 3a, has space inside the housing body 20, the four identical hinge elements 46 are in each case mounted in a mirror-inverted manner, wherein naturally other options of hinge elements 46, which define a parallel guiding are also possible.

(20) The hinge elements 46 are in this embodiment rigid and define two axes at the connections to the housing body 20 or the housing door 30. The first rotation axis 41 is defined at the connection of the hinge elements 46 and housing body 20, the second rotation axis 42 is defined at the connection of the hinge elements 46 and housing door 30.

(21) In the cross-section of FIG. 3, the formation of the sealing edge 26 can be seen particularly clearly. FIGS. 3b to 3d show the housing door 30 with a progressive degree of opening.

(22) Finally, FIG. 4 is a perspective view of the housing door 30 according to the second embodiment in an open state. The arrangement of the components inside the housing 10 is in this instance different from the arrangement of the first embodiment, wherein also any other arrangements of components in housings 10 according to the invention can be used.
